Public bug reported:

I used to be running Ubuntu 9.10 on a notebook computer with a secondary
screen. Several weeks ago the primary monitor (the notebook screen)
started refusing to display anything, not even the bootloader (grub)
menu. (It did, however, switch on and off the backlights while booting.)
I tried switching to the proprietary NVidia drivers but it was the same
thing. So I assumed that the screen was broken, and bought a new
notebook computer (what good is a notebook if you need a separate
screen).

When I tried to boot this new computer with a 9.10 live cd it displayed
the start menu (try, install, memory check etc.) but the display went
blank as soon as I chose any other function but "memory check". The cd
drive's activity showed that the computer was busy but it would not let
me see what it was doing. I checksummed the live cd, burnt another live
cd at minimum speed -- nothing helped.

So I downloaded a 9.04 live cd, and could install it without any
problems. Everything is displayed without problems on the primary
monitor. (I finally had to go back to 8.04 for lack of the proper
network driver in 9.04 but that is another story.) So some kind of
regression seems to have happened between 9.04 and 9.10, if you consider
using the primary screen an asset.

I searched for bug reports about "primary screen" or "dual monitor" but
found nothing that matched my problem. Maybe bug 462168 is related to
this one but, unlike there, my blanked screen never displays a mouse
pointer.

I can provide further data if somebody tells me what could be useful.
